Few charges exist in 3-D space. The potential due to the system of charges at an origin depends on:
A. The magnitude of each charge.
B. The distance of each charge from point P.
C. The angles between the position vector of each charge make with the x, y, and z axes.
1. Only A and some constants
2. Only A, B and some constants
3. A, B and C and some constants
4. independent of all the above quantities
